Urine Reagent Strip (Glucose-Protein-pH)

Urine Reagent Strip (Glucose-Protein-pH) description:

Los Angeles-based Diagnostic Automation/Cortez Diagnostics, Inc. offers a Urine Reagent Strip (Glucose-Protein-pH) Rapid Test for the semi-quantitative and qualitative detection of Glucose, Protein, and pH in urine. The Urine Reagent Strip for Urinalysis is for in-vitro diagnostic use only.

The Urine Reagent Strip (Glucose) Rapid Test is based on a double sequential enzyme reaction. One enzyme, glucose oxidase, catalyzes the formation of glucomic acid and hydrogen peroxide from the oxidation of glucose. A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with potassium iodide chromogen to oxidize the chromogen to colors ranging from blue-green to greenish-brown through brown and dark brown. The test area is specific for glucose; no substance excreted in urine other than glucose is known to give a positive result. Approximately 100 mg/dl glucose in urine is detectable.

The Urine Reagent Strip (Protein) Rapid Test is based on the protein error-of-indicator principle. At a constant pH, the development of any green color is due to the presence of protein. Colors range from yellow for a Negative reaction, to yellow-green and green to blue-green for a Positive reaction. The test area is more sensitive to albumin than to globulin, hemoglobin, Bence-Jones proteins, and mucoprotein; a negative result does not rule out the presence of these other proteins. The test area is sensitive to 15 mg/dl albumin. Depending on the inherent variability in clinical urine, lesser concentration may be detected under certain conditions.

The Urine Reagent Strip (pH) Rapid Test is based on the well known double pH indicator method, where bromothymol blue and methyl red give distinguishable colors over the pH range of 5-9. The colors range from red-orange to yellow and yellow-green to blue-green. The test area permits quantitative differentiation of pH values to one unit within the range of 5-9. pH reading is not affected by variation in the urinary buffer concentration.Notable features of the Urine Reagent Test Strip (Glucose-Protein-pH) Rapid Test: • reliable and inexpensive • easy-to-understand directions • clear preparation and storage procedures • simple specimen collection directions • safe and convenient packaging • rapid and accurate test results
